This invention relates to certain new and useful improvements in street lighting fixtures and refers more particularly to means for mounting glassware to ornamental standards or posts. r

In street lighting fixtures of tl ns type, a glass bowl, usually of ornamental configura tion, surrounds the lamp to diffuse-its light, and heretofore it has been customary to attach such glassware to a supporting .mem-' ber at the'top of the post or standard by means of screws or other similar means which directly engaged the lower periphery of the bowl. This method of mounting the glassware has been objectionable for the reason that'attaching means located only at the bottom of the bowl caused considerable strain to be imposed on the glassware during strong winds. This direct application of unyielding mechanical pressure produced by tightening the attaching screws also very often cracked the bowls.

Means were therefore devised whereby the glassware was rigidly held not only at its bottom, but also at a medial point, but ex isting devices for this purpose are costly and have proved objectionable in that a considerable shadow was cast by the external supporting structure. It is, therefore, an object of this invention to provide means for mounting glassware of the character described which is entirely concealed andprovides a firm but yielding means of attachment.

Another object of this invention resides in the provision of means for anchoring glass- Wars of the character described to its supporting structure, which is applied .to the glassware at a point spaced considerably from the support to increase the stability of the glassware. i

A more specific objectof this inventionresides in the provision of spring means for anchoring glassware of the character describedto its supporting structure which is adapted to be concealed within the glassware to provide a resilient but firm means of attachment.

And a further object of this invention resides in the provision of an anchoring means 1930. Serial No} 444,182.

With the above andother objectsin. view which will appear asthe description proconstruction, combination and arrangement of parts substantially as hereinafter described and more particularly defined by the appended claims, itbeing understood ceeds, my invention resides in the novel that such changes in the precise embodiment .T

of the herein disclosed invention maybe made as come within the scope of the claims.

In the. accompanying drawings, I have illustrated one complete example of the physical embodiment of my invention .constructed according to the best model have so :far devised for the practical application of the principlesthereof, and in which? Figure l is aside'elevationalyiew of a lighting. fixture embodying my invention, parts thereof being broken away to illustratestructural details; and

F'gure 2 is a detail sectional view taken through Figure'l -on the plane of the line Referring now moreparticularly to the accompanying drawings, the numeral 5 rep-. resents the top of austreet lighting standard or postwhich is known in the art as a capital and which formsthe direct support for .the fixture, indicated generally bythe numeral 6Q The fixture 6 may be of any desireddesign and comprises a socket receptacle? supported from the capital 5ito. receive a conventional 1 socket 9 mounted therein.

8 having a bulb The bulb and itssuppiorting structure is enclosed .in a bowl 10 formedof glass and usually of ornamental design. Thelower end of the bowl rests on a rubberv or other yieldable gasket llforming the bottom of an annular channel 12 which may be part of the capital or may be formed in an adaptor ring 13 secured to the top of-the-capital.

vA plurality of contractile springs 14 having their opposite ends hooked over the top peripheral edge 15 ofthe bowl lO' and in apertures 16 formed in lugs 17 projected inwardly from the adaptor ring 13, hold the bowl in position. By attaching the springs to the upper portion of the bowl, maximum stability is obtained and the bowl is held in compression at all times.

The open top of the bowl is preferably closed by a separate hood or dome section 18 which may be formed of glass to complete the design of the fixture. An ornamental metal ring 19 servesto connect the dome 18 with the bowl 10, the upper marginal edge of the ring being'directed inwardly, as at 20, to overlie the outwardly directed peripheral edge 21 of the dome 18, and a yieldab-le gasket 22 being preferably" provided between the flange 20 and the outwardly directed portion 21.

The peripheral edge portion 21 of the dome telescopes over the adjacent edge of the bowl 10 and'rests on the hooks of the springs 14, but if desired, the top marginaledge of the bowl 10 may be notched at in- ,tervals about its periphery for a depth sufficient to receive the hooks of thesprings and allow the dome to rest directly on the top edge of the bowl. Screws 23 threaded in the ring 19 at intervals about its circumference engage in an annular channel 24'formed at the top of the bowl 10 to maintain the ring 19- and the dome 18 rigidly connected with the bowl. i

From the foregoing description taken in connection with the accompanying drawings, it will be readily apparent to those skilled in the art to which an invention of the character described appertains, that I providea novel inexpensive means 'for anchoring glassware of street lighting fixtures to their supporting structures, which greatly in creases'the stability of the mounting and provides a positive and firm attachment without imposing direct mechanical strains on the bowl I and wherein the anchoring means is entirely concealed.

What I claim as my invention is:

1. In a lighting fixture of the character described comprising a support, -a two part glass bowl mounted on said support, resilient means engaging one part of said bowl between said parts to resiliently urge said bowl ontosaid support, said other part being superimposed cn'the first part and on said means, and joined to said first part through an ornamental metal ring,'substantially as described.

2. In an ornamental lighting fixture of the character described, a support, a two part glass bowl. supported from said support and permitting access to the lighting fixture by removal of one ofsaid parts, resilient means engaging one part of said bowl between said sections and at'spaced points about the periphery thereof to resiliently urge said last named part of said bowl .onto said support, means removably retaining said other section in juxtaposition tion to resiliently urge said bowl onto said.

support, said other section being superimposed on said first section and on said means, a metal ring having a flange engaging said last named section and means engaged with said ring and with means on said first named section to hold the two sections in juxtaposition;

4:. In a lighting fixture of the character described, comprising a support, a two part glass bowl mounted on said support, said bowl comprising an upper section and a lower section resilient means engageable with the upper edge of the lower section and engageabl with said support for constantly urgingsaid lower section onto said support, an annular outstanding flange on said per section forming a seat for said bowl on said resilient means, a metal band having an inturned annular fiangeseated on the upper side of said outturned annular flange and means on said band cooperating withmeans on the lower section of said bowl to hold the two sections of said bowl in juxtaposition.

In testimony whereof I have hereunto aflixed my signature.

GEORGE H. COLE.
